The idyllic Holzhausen Castle is situated in the middle of a lake in Holzhausen Park. Built in 1727 to 1729, the castle was once the Holzhausen dynasty's country residence. The Rococo building changed hands when it was taken over by the city of Frankfurt in 1923. Tranquil and exuding a peaceful charm, the castle was designed by French architect Louis Remy de la Fosse with Flemish and Nordic inspired architectural styles. The castle and its lush grounds are used today primarily for social and cultural events.
